Power Steering Cooler Return Hose, Rein - E46 323i/325i/328i/330i

This part is listed by BMW as BMW part number 32416796390 (32 41 6 796 390) and is described as Power Steering Hose from Reservoir to Cooler for E46 323i 325i 328i 330i.

BMW has two hoses they call a Return Line - this is the hose running from the power steering cooler to the reservoir. It returns fluid back to the reservoir. Like the Inlet/Supply Hose it has non-reusable crimped hose clamps where the hose meets the reservoir. Leaks are very common here as the clamps loosen and the rubber hose swells.

BMW uses a “quick disconnect” plastic fitting on some hoses that can be finicky to remove (push fitting further on the pipe, compress plastic collar, then pull apart). We strongly recommend having the QD fitting tool in your toolbox - see Related Items below.

This is an E46 PS hose manufactured by Rein - an original supplier to BMW for many other suspension and steering components. As an OEM it meets all of BMW's original design, fitment, and performance requirements. OEM parts are the best alternative to more expensive Original BMW parts because they are virtually identical without the inflated price tag. This part has a two year warranty.
